Re: Can PSUs Cause Bad Caps?
really. the newer ones i heard were holding up better in power supplies, like teapo. honestly.
the old ones are shit, i know that.
the one i have now still runs great... i put in my dad's computer... if it was shit, i would not be giving it to him...sigpic

Re: Can PSUs Cause Bad Caps?
RLS isn't new.
Neither is a PSU that went in production in '05 and out of production in '06.
If I look around I probably even have some bloated RLS from '05 & '06.
I had a batch of FSP units loaded with them.Mann-Made Global Warming.

Re: Can PSUs Cause Bad Caps?
OST has always been similar to Teapo and LTEC. Can be OK in a well cooled PSU but Only Some Trash on motherboards. Personally, they are not up to my quality standards so I re-cap all three of those brands in a PSU I intend on using/keeping, bloated or not.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Can PSUs Cause Bad Caps?
Have any of you seen any solid state capacitors in PSUs or motherboards go bad?
Some companies advertise how they use Japanese solid state capacitors with their products. Are all brands of Japanese solid state capacitors generally regarded as high quality caps?Comment

Re: Can PSUs Cause Bad Caps?
Solid State Capacitors would be capacitors formed into the silicon in IC chips..
-- RAM and is essentially banks of Solid State Capacitors.
-- Flash memory [including that in a BIOS Chip] is the same as RAM in that.
So when you see bad RAM or a bad BIOS chip you are seeing bad Solid State Capacitors.
Solid Polymer, Functional Polymer, and Organic Polymer caps [as various manufacturers call them] aren't solid state parts despite various advertising campaigns.
Any part can fail.
The failure rate of the various Polymer cap varieties is very low...
... probably somewhere around what it is for transformers.
~~~
Watch out for electrolytics that -look like- Polymer but aren't.
Sacon FZ are the the famous one but there are many others that don't get noticed because they don't fail in droves like the Sacons.

A while back I thought Capxon had 'become okay' in PSUs too but I've revisited that idea and changed my mind.
Seen too many blown Capxon in LCD's & TV PSUs w/ dates as new as 2008. Last week I cracked open an FSP 700 watt [built late 2006] and its packed with swollen Capxons. [The damned things are 8mm x around 30mm at 2200uF ... WTF-over?]
I see less OST than Capxon these days so I see less bad OST than Capxon.
... But if I see 100 Capxon and then 100 OST the - % - of either that is failed would be about the same. [My guess is about 50%.]
... If I added 100 Teapo to that comparison there the failure rate for Teapo would probably be less than 5%. [Better but not great.]
[But anymore Teapos mostly show up as primaries or 6.3mm and smaller caps except in total crap brand PSUs.]

Re: Can PSUs Cause Bad Caps?
I have yet to see one of these AcBel units fail, in the 2 or so years I've been using them. Of course that doesn't mean that they won't fail at some point, but so far they've worked fine.
OBTW, concerning the 70% efficiency. That is probably a worst-case number, similar to their stated ripple specs. I can tell you that running in my computer this AcBel is nowhere near as high on ripple as they rate it.A man convinced against his will is of the same opinion still.Comment

Re: Can PSUs Cause Bad Caps?
Ads always give peak [best] efficiency.
That usually occurs at around 75-80% of rated max load.
It's less above and below that.

Re: Can PSUs Cause Bad Caps?
Would they not be considered to be lying if they published that efficiency was greater than or equal to 70% when it wasn't?
Then why even publish it?A man convinced against his will is of the same opinion still.Comment

Re: Can PSUs Cause Bad Caps?
They don't want to say 73% and then get sued because some units only manage 71%.Mann-Made Global Warming.
